-KEROPLANE.' I

a citizen of the United States, residing at New York, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Aeroplenes, of whichthe following is a specification,reference being had therein to the accompanying drawing.

My invention relates especially to the construction and arrangement ofthe planes in aeroplanes, and has for its object the provision of asimple and effective device whereby, the Compression of the air belowthe planes is insured and the air cannot escape at the ends of theplanes.

To attain the desired end, my invention consists in certain novel anduseful combinations or arrangements of parts, and peculiarities ofconstruction and operation, all of which will be hereinafter first fullydescribed, and then pointed out in the claims. .In the drawings, Figure1 is a perspective view of an aeroplane embodying my invention. Fi 2 isa modification of the arrangement illustrated in Fig. 1. Fig. 3 isa'vertical sectional view at line a-a of Fig. 2.

Like numeralsof reference, wherever they occur, indicate correspondingparts in :11 the figures.

1 are planes made of any approved material the front plane being thelower one.

2 are side-pieces to which the planes are connected and secured. In Fig.1 I have shown the side-pieces as flat and extending at right angles tothe planes. In Figs. 2 and 3 the side-pieces are shown assemicylindrical, the concave sida being inside, or next to the planes.

3 are vertical rods extending downward from the planes and carrying aplatform 4 for machinery. operatives, etc. 1

It will be observed that the planes are located one above the other, theedge of each succeeding plane overhanging the plane below it, anarrangement best calculated to obtain the greatest efiiciency of thedevice.

Any number of planes may be used. of

any desired width and length, and the planes D to the other plane invertical direction .not

may be any proper distance apart, as these details of arrangement may begreatly varied without departing from the spirit of my invention, and itwill beifound t iat my iin roved aeroplane obtains the greatest-possib esustaining capacity proportionate to u 'Specificationotlctterslatent.Application filed October 2?, 190a. set-mire. 524,884.

vvthe snrface of the planes and by reason of the combination with theplancsof the sidepieces, the sustaining air is confined and compressedand cannot escape at the ends ofthe planes. w

' Having now fully described my invention, whatI claim as new therein,and des re to secure by Letters Patent, is:-

1. In an aeroplane, a plurality of planes of any desired widths arrangedin series the front one being the lower one each plane extending overthe preceding plane not more than one-third the width of the prc-'ceding plane in combination with air confining side pieces carried bythe planes and extending above and below the same substantially as shownand described.

2. In an aeroplane a plurality of planes of any desired widths arrangedin series,

the front one being the lower one. each plane extending over thepreceding plane, not more than one-third the width of the precedingplane, the distance from one plane to the other plane in verticaldirections. not. being limited in combination with curved side piecescarried by the planes and extending above and below the same.
